Answer 1

The formula for the separation between the plates, d = V/E and d = 1.02 mm

Step-by-step explanation:

Here is the complete question

The electric field strength between the plates of a simple air Capacitor is equal to the voltage across the plates divided by the distance between them When a voltage of 112. V is put across the plates of such a capacitor an electric field strength of 1.1 kV/cm is measured. Write an equation that will let you calculate the distance d between the plates. Your equation should contain only symbols. Be sure you define each symbol

Solution

The electric field strength between the plates of a simple air capacitor is given by E = V/d where V = electric potential between the plates and d = separation between the plates.

Making d the separation between the plates subject of the formula, we have

d = V/E

Since V = 112 V and E = 1.1 kV/cm = 1100 V/cm

Substituting the values of the variables into the equation, we have

d = V/E

d = 112 V/1100 V/cm

d = 0.102 cm

d = 1.02 mm

So, the formula for the separation between the plates, d = V/E and d = 1.02 mm.
